VENTILATING APPARATUS FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 404,196, dated May 28,1889.

Application filed August 23, 1888. Serial No. 283,563. (No model.)

To all whom it may concern.- I

Be it known that I, J EssE L. HUTCHINSON, of the city of Baltimore, inthe State of Mar land, have invcnted'certain Improvementsin VentilatingApparatus for ater-Closets, of which the following is a specification.

This invention relates to improved means for effecting an upward currentin the ventilating-pipe which leads from the soil-pipe of awater-closet, as will hereinafter fully appear.

It is well known that in ventilating-pipes of the character alluded tothere is practically no upward current unless the heavy foul air thereinbe rarefied by the application of heat to the pipe. In some cases thecontained air is rarefied by applying to the ventilating-pipe agas-flame, and in others the said pipe is run so as to be heated from aflue. The first of these methods is attended with considerable expense,as the gas-flame has to be constantly maintained. The second methodcannot be easily employed when the water-closet is not in the vicinityof a flue constantly in use.

My invention consists in combining with the ventilating-pipe, areservoir of air or water under pressure, and a pipe containing asuitable self-closing cook or valve, whereby, either in the use of thecloset or by the movement of some device connected with the said valve,a current of compressed air or wateris admitted to the interior of thesaid ventilating-pipe in an upward direction and the foul air thereinset in motion.

In the further description of the said invention which follows referenceis made to the accompanying drawings, forming apart hereof, and inwhich- Figure 1 is a partly sectional view of the principal parts of awater-closet provided with myimproved ventilating apparatus, and Fig. 2a detail of the same on an enlarged scale.

Similar letters of reference indicate similar parts in both views.

In the said drawings, A represents the bowl of the water-closet, and 13the trap, which empties into the soil-pipe C.

D is the ventilating-pipe, which consists in the present case of acontinuation of the soilpipe and extends to a point above the roof ofthe building in the usual way.

E is a reservoir of compressed air, connected to the interior of theventilating-pipe by means of a small pipe, or, in which is a cook orvalve, 1), having a small discharge-aperture. The handle 0 of the cockI) may be opened by hand through the medium of a chain, if desired; butit is preferably attached to the seatof the closet, which in that casewould be of the hinged descriptioinbya wire or chain, as shown in thedrawings.

I do not restrict myself to any particular means for obtaining a body ofcompressed air or water in a reservoir, asthis can be eff ected in avariety of ways; butin cases where the ordinary flushing-tank can beapplied I secure a body of compressed air by dividing the said tank,which is represented in the drawings by F, by a flexible diaphragm, (Z.The lower chamber is then used as a receptacle for water and the upperone for air, which is compressed as the water-chamber is filled by theupward movement of the flexible diaphragm. In Fig. 1 the diaphragm isshown in its lowest position in full lines and in its highest one by thedotted line.

WVith the construction described the airchamber would have to beprovided with a check-valve, e, to admit air and at the sametime-prevent its escape. The pipe for supplying the water-tank isdenoted by g. This pipe may have a valve to control the flow of waterthrough it; but such valve is not'necessary if the pipe is madeconsiderably smaller than the discharge-pipe H, which leads to the bowl.ith pipes arranged in this manner the filling of the Water-tank willb'egradual, while the discharge to the bowl will be sudden. I

The flushing-pipe H is provided with a valve, I, and the seat with atrigger, J, which, as the hinged seat is elevated, opens the valve for aperiod and effects the flushing of the bowl. The exact arrangement ofthese valves and the trigger is no part of my present invention, anddoes not, therefore, require any special description.

lVhen the invention is arranged as shown in the drawings, a current ofcompressed air is conducted to the interior of the ventilating-pipe inthe act of using the closet; but, as before stated, it may be applied byhand independently of the seat of the closet, if desired. As the waterin the tank is discharged to flush the bowl, the flexible diaphragmfalls and air enters the upper chamber through the check-valve e and iscompressed as the water-tank is again filled. By this means the closetis at all times provided with a body of compressed air, which may bedischarged to the ventilating-pipe to form an upward current therein byhand or automatically, as described.

I claim as my invention 1. In combination with the ventilating-pipe of aWater-closet, a reservoir of compressed air or water, a pipe leadingfrom the said reservoir to the interior of the ventilating-pipe, aself-closing cook or valve in the said conneeting-pipe, and a chain orwire whereby the said cock or valve may be opened and a current of airor water admitted to the interior of the said ventilating-pipe,substantially as and for the purpose specified.

2. In combination with the ventilating-pipe of a water-closet, areservoir of compressed air or water, a pipe connecting the saidreservoir to the ventilating-pipe, a cook or valve in the saidconnecting-pipe, a movable seat, and a connecting chain or wire, wherebyin the movement of the seat the said cock or valve is opened andcompressed air or water admitted to the interior of the saidventilating-pipe, substantially as and for the purpose specified.

In combination with a water-closet and a ventilating-pipe leadingtherefrom, a tank having a flexible diaphragm therein which divides itinto two compartments, one of which is provided with a water-pipe tofill it, and a discharge-pipe for flushing the water-closet bowl, andthe other compartment fitted with an inwardly-opening air-check, and adis charge-pipe leading to the ventilating-pipe, having therein acontrolling valve or cock, substantially as and for the purposespecified.

4. In combination With the ventilating-pipe of a water-closet, a tank, aflexible diaphragm to divide the tank into two compartments, one for airand the other for water, suitable pipes connected with thewater-compartment, whereby the same is filled and discharged, andanother pipe leading from the air-compartment to the saidventilating-pipe, whereby in the filling of the Water-con'lpartment airis compressed in the other and forced in to the ventilating-pipe,substantially as and for the purpose specified.
